SCNView : setting "overlaySKScene" doesn't render anything

I have struggled long and hard with this .. I think I’ve looked at 'everything' related on Google, but I’m still flummoxed.

This is on Mac OS 10.11.3, build with Xcode 7.2, and this is what I think is the salient code.

    override func viewDidLoad() {
        super.viewDidLoad()

        let scene = SCNScene()
        let sceneView = self.view as! SCNView

        sceneView.scene = scene
        sceneView.overlaySKScene = OverlayScene(size: sceneView.bounds.size)
        sceneView.backgroundColor = NSColor.blackColor()
        sceneView.autoenablesDefaultLighting = true
        sceneView.showsStatistics = true
    }

('OverlayScene' generates a simple SKScene with some centered text)

On the Mac it works correctly if the window layout is described by a XIB.
On the Mac it doesn’t show the overlay if the window layout is described by a Storyboard.

The XIB and Storyboard are quite different (as is normal), but what in there could have this effect?

Any help to resolve this would be appreciated .. I suspect, as is often the case, I’m overlooking something obvious .. Thanks

FWIW: This same code works correctly on iOS using a Storyboard.
